Integrated BioPharma is a contract manufacturer of vitamins, nutritional supplements, and herbal products. The company primarily operates through its subsidiary, Manhattan Drug Company, which produces finished supplement products in capsule, tablet, and coated forms for third-party brand owners, direct selling companies, and specialized healthcare providers. Customers either provide their own product formulations or collaborate with Manhattan Drug Company to develop them. Integrated BioPharma does not sell products under its own consumer brands and does not invest significantly in proprietary research and development. Instead, its business model centers on operational execution, product quality, manufacturing reliability, and customer service. Revenue is driven by purchase order volumes without long-term purchase commitments, with high customer concentration in Life Extension and Herbalife. In addition to contract manufacturing, the company operates an ancillary segment that provides warehousing and fulfillment services, as well as raw material distribution.
